Unbreak syscons' support for ddb mode by reactivating old fixes

Browse Source 
(syscons.c 1.331 and 1.372 are reactivated by restoring this part of
db_interface.c (i386 version 1.48, ...) in a different file).

This is not a MFC because larger changes than I have time for are
needed there.

The most noticeable effect of this fix is that syscons switches to the
console vty on entry to ddb.  The most important effect of this fix
is that switching vtys in ddb doesn't try (and sometimes succeed) to
crash the system by calling wakeup().
